  EDSA Induction Motor Parameter Estimation

EEDSA’s Induction Motor Parameter Estimation program provides an estimate of equivalent circuit parameters for induction motors. This estimate is useful for motor starting or re-acceleration performance simulation studies.
 
  The estimation is based on data that are readily available from the manufacturer, or can be obtained from field tests. Estimated parameters include the resistance and reactance representing the stator, rotor and magnetizing branch.

    Parameter estimation is based on an extremely robust optimization technique, sequential augmented Lagrangian optimization algorithm.) It has great flexibility to handle constant and finds the best possible motor equivalent circuit parameters to minimize the difference between specified motor performance data (published or test results) and the corresponding performance parameters of the equivalent circuit.  
       

 
     
    Key Program Features:
    The analysis provides an estimate of the equivalent circuit parameters for induction motors. The estimated pparameters are:
     
  • R1 Stator Resistance (Ω);
  • X1 Stator Reactance (Ω);
  • R2 Rotor Resistance (Ω);
  • X2 Rotor Reactance (Ω);;
  • RM Magnetizing Branch Resistance (Ω);
  • XM Magnetizing Branch Reactance (Ω);
  • CR Rotor Resistance Cage Factor (dimensionless);
  • CX Rotor Reactance Cage Factor (dimensionless).
